Articular cartilage does not contain blood vessels, the nutrition of chrondrocytes being derived mainly by diffusion of synovial fluid (Stockwell and Barnett, 1964; Ekholm, 1951). It has been demonstrated that the permeability of articular cartilage diminishes with ageing (Stockwell and Barnett, 1964; Tsaltsas and Kyriazis, 1967). This change has been attributed not only to the physical changes...

INTRODUCTION In an increasingly old society, the study of the respiratory system changes and new techniques dedicated to older patients are of interest in physiologic studies as well as in the diagnosis of respiratory diseases. OBJECTIVES (1) To investigate the impact of ageing on the resistive and reactive properties of the respiratory system, and (2) to compare the easiness of accomplishmen...

The study was conducted to test whether a vigor of single count radicle emergence (RE test) would correlate with the storage potential 10 seed lots onion (Allium cepa L.) cultivars in artificial conditions. RE performed by counting (2 mm) percentage at 80 h after germination set up 20 °C. Seed longevity determined 75% relative humidity, obtained saturated NaCl, 35 °C over 60 days. Twelve sample...

With the further deepening of ageing in China, ageing-in-place model is gaining more and attention. In order to improve quality home life elderly, this paper takes age-friendly cabinets as research object, from perspective material design, visual/tactile experience elderly entry point, classifies current market cabinet materials, selects test samples. The physical properties samples were examin...

The design of axially loaded piles has been an area focus for the offshore industry in recent years. A number studies report substantial increases shaft capacity driven sand, known as pile ageing. slow to implement ageing into practice because uncertainty over mechanisms controlling and variability on impact This paper presents results tests using instrumented with two separate installations co...
